Okay. If we're gonna play the "google sites and link them and call it effort" game, then here you go.

"In addition to the paper from Bhatt and his colleagues, Nature also published a separate study from the Global Policy Lab at the University of California, Berkeley. That study analyzed lockdowns in China, South Korea, Iran, France, Italy and the United States. It found that the lockdowns in those six countries averted 62 million confirmed cases."
The WHO article you linked states immediately before your quote that "WHO recognizes that at certain points, some countries have had no choice but to issue stay-at-home orders and other measures, to buy time."
The WHO article you linked states immediately after your quote that "Governments must make the most of the extra time granted by ‘lockdown’ measures by doing all they can to build their capacities to detect, isolate, test and care for all cases; trace and quarantine all contacts; engage, empower and enable populations to drive the societal response and more."
Let's analyze that last bit there. In your opinion, exactly how good of a job did the United States Government do of engaging, empowering, and enabling populations to drive the societal response to Covid-19?
Let there be no mistake. If it weren't for the "shutdown" that our country entered into at the start of this pandemic, we would have had a ton of overflowing hospitals. I don't care how many articles you can find that argue otherwise, that's just sheer common sense. You're right, I must admit that ideally, the lockdown wouldn't have gone on for nearly as long as it had to, because ideally we would have been unified by this threat like we were by 9/11 or a catastrophe of that sort rather than being divided. But we, the American People, chose to fuck ourselves instead.
